An Indiannavy submarine caught fire after an explosion and sank early on Wednesday at its home port in Mumbai.

The fire was extinguished but the official said the sailors have not been rescued and it was unclear whether any were killed or injured.

When the blast occurred, some sailors of other nearby units jumped into the sea in panic. It is unclear how many sailors were killed or injured.

A Navy spokesman said efforts were being made to determine the safety of the personnel and salvage the submarine.

The 16-year-old Russian-made submarine, INS Sindhurakshak, had recently returned from Russia after undergoing an overhaul and upgrade, according to an analyst for the independent Jane's Information Group.
